INFLUENCE OF STRESS HISTORY ON REMOULDED COHESIVE SOILS

Soils with a wide range of plasticity were compressed in a one-dimensional cell up to 2200 p.s.i. with subsequent rebound to zero stress. There is a relation between coeff. of earth pressure and the drained angle of internal friction and with plasticity. In medium and high plasticity soils a laminar structure appeared and after the test a jointed structure was observed for all soils suggesting that structures of these types in preconsolidated deposits are due to stress history.
